Building in Existing Contexts and Energy Refurbishment

Building in Existing Context and Energy Refurbishment

This module addresses issues in existing buildings: from historic materials and their rehabilitation to the handling of pollutants and systems for energy modernization.


The various existing buildings with their typical building materials and structures are subject to numerous damage processes over their useful life due to the effects of weathering or mechanical loads. In the lecture, the basics of renovation measures are presented in detail and clearly conveyed with numerous examples from the areas of half-timbering, concrete, stone walls, etc.. The spectrum of refurbishments covers historical building materials, but also addresses modern usage requirements and corresponding refurbishment concepts.

All necessary measures for the maintenance and repair of structures are presented. The relevant standards are just as important as the basic understanding of the interlocking materials and techniques. Ultimately, it should be possible to select professional steps and at the same time avoid inadequate and damage-prone procedures, e.g. in connection with moisture loads and waterproofing measures.

Emphasis continues to be placed on early assessment of system deviations in order to prevent the development of major, sometimes irreparable, damage.

The course usually includes a laboratory practical, an excursion and a student performance in the form of a paper on a relevant topic.
